Low-loss thin-film periodically poled lithium niobate waveguides fabricated by femtosecond laser photolithography
Guanghui Zhao, Jintian Lin, Renhong Gao +10
Periodically poled lithium niobate on insulator (PPLNOI) ridge waveguides are critical photonic components for both classical and quantum information processing. However, dry etchi…

Erbium-ytterbium co-doped lithium niobate single-mode microdisk laser with an ultralow threshold of 1 uW
Minghui Li, Renhong Gao, Chuntao Li +9
We demonstrate single-mode microdisk lasers in the telecom band with ultra-low thresholds on erbium-ytterbium co-doped thin-film lithium niobate (TFLN). The active microdisk were f…
